Bob;
Yes, now if the weather will just co-operate! We have 24 degrees F and about 3 inches of sleet all over the ground. Looks like I will not be able to get out until Monday or Tuesday. In the meantime I can do some more on the chassis. I have one lead of the IF/2nd. Detector transformer (blue wire) that I am trying to pinpoint where to connect it. It looks like it was originally connected to pin 5, but the schematic seems to indicate it should be grounded. More checking to do.
I had to look back at my under the chassis photographs and saw that the wire in question went to R45, a 330K ohm 1/2 watt resistor, so I solved that problem and the IF transformers are all connected now. I have hook-up wire kits, both stranded and solid wire in multiple colors coming from Jameco. I will have to have those before I can resume replacing any more of the rubber coated wiring. Some of the wires look really likely to short to another wire.
